The reason a magnet cannot attract aluminium is because aluminium is not a magnetic material. Magnets can only attract objects that are made of iron, nickel, cobalt, or certain alloys of these metals.
No, all types of magnets, including permanent magnets and electromagnets, cannot attract aluminium. This is because the properties of aluminium do not allow it to be magnetized.
Some aluminium objects may seem to stick to magnets, but this is actually due to the presence of iron or other magnetic materials in the object. For example, aluminium foil may stick to a magnet because it is coated with a thin layer of iron oxide.
No, it is not possible to make pure aluminium magnetic. However, it is possible to create a magnetized aluminium alloy by mixing aluminium with other magnetic materials such as iron or nickel.
No, the strength of the magnet does not affect its ability to attract aluminium. As mentioned before, aluminium is not a magnetic material and cannot be magnetized, so even the strongest magnets cannot attract it.
